Passively cooled components are becoming ever more in demand these days as people are looking for quiet solutions that are still high performance. Recently we took a look at one of those as we reviewed Powercolor’s HD 7850 SCS3 passively cooled graphics card and if you haven’t already seen that then we encourage you to check that review out here. However, we had some feedback about the product with readers and Powercolor themselves enquiring whether we could test it with fans to show how effective the heatsink design really is. Today we are going to do exactly that as we put the PowerColor HD 7850 SCS3 through its “thermal paces” in passive mode, with a 120mm fan and with a 140mm fan.

We will be using a Prolimatech Vortex 12 Blue LED Fan at 1200RPM for the 120mm fan test and a Noctua NF-A14 ULN fan at 800RPM for the 140mm fan test. This way we have high performance fans but tamed at an RPM that most users would still find very quiet or near-silent which is what you will really want if you’ve bought a passive graphics card and just want to give it a little extra “helping hand” with airflow.

But without any further ado let us proceed and take a look at the temperature and noise results!

Hopefully PowerColor will put some thought into making it easy to attach a fan (and detach the fan for cleaning – one of the problems with using zip ties) on their next SCS3 card.

How do you secure each fan using what hardware could have been a help since some of us may like this setup after all.
Please add that info with pics or diagrams instead of used 2 wireties OR 2 wirenuts and ####

wire-ties through the rear fan holes and attach to whatever it can grip onto. The top of the fan to heat pipes and the bottom to heatsink.

How the hell do you call this crap a review when you show no benchmarks or even the cards specs? And you actually get paid for this crap?
